Disclosed is an apparatus and method for obtaining images using coherent anti-stokes Raman scattering. The apparatus for obtaining images using coherent anti-stokes Raman scattering according to the present invention comprises: a pump light source and a stokes light source that irradiate pump light and stokes light on a sample to generate anti-stokes light having anti-stokes frequency; a reference light source that generates reference light; and an image obtaining unit that obtains the images of the sample using a change in phase of the reference light due to a change in the refractive index of the sample in the vicinity of the anti-stokes frequency. Thereby, the present invention can provide the apparatus for obtaining images using coherent anti-stokes Raman scattering that is not affected by a non-resonant background signal phenomenon, strong resistance against noise even in a weak signal, and has excellent sensitivity and resolution.
